Welcome to Gaia. If you play heralds of chaos on survivor mode which can be found in announcements for heralds of chaos page 6. You can earn after 5 times of playing 5000 essence to transfer to 50,000 gold. How I went from noob to middle class
Asking for help, like you just did, is a good way to start.
Just about everything at Gaia is organized around its commercial economy, so:
Watch videos for Gaian cash. Click on the cash icon, up where your gold, cash, and achievements stats are displayed at the top of the page. Watch videos for cash. That will get you started.
You get gold for every time you post or comment, so find a forum or some forums where you feel comfortable, and talk to others.
The game of Booty Grab is a good way to snag some extra gold. While you're posting in the forums, look for aquariums that suddenly are displaying the words BOOTY GRAB.
Log in every day, even if only for a few minutes, and click on the orange machine-thingy on the right side of the Gaia banner. Do this on each page: Home, My Gaia, Shops, Forums, World, and Games. You get gold and items (some of which are salable in the market).
Buy and sell things. You can buy the Monthly Collectible Letters for 250 cash, and then sell them on the market (or open them and sell what's inside). This will get you started in the market.
Other than that, do what you're interested in. Games, roleplaying, posting, chatting?
